Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle-mounted fan technical field, concretely is a kind of vehicle-mounted brushless motor and fan with communication control. BACKGROUND

[0002] Vehicle-mounted fan is indispensable component of automobile, mainly for temperature regulation, air circulation, defogging, to improve the comfort of driving.

[0003] Vehicle-mounted fan is generally driven by brushless motor, because brushless motor has the advantage of low noise.

[0004] Vibration will be generated in the process of automobile driving, and traditional brushless motor is in hard contact with vehicle frame, especially brushless motor with communication control (communication control is connected with vehicle control panel signal, so that driver controls brushless motor by operating vehicle control panel), therefore brushless motor is easy to be damaged under vibration. Especially, brushless motor is in radial contact with large area, so brushless motor is more easily stressed in radial direction, so that communication control is easily damaged.

[0005] Therefore, how to protect communication control on brushless motor under automobile vibration and avoid its damage becomes a problem to be solved by the person skilled in the art. SUMMARY

[0006] To solve the technical problem in the background art, the utility model discloses a kind of vehicle-mounted brushless motor and fan with communication control.

[0007] The utility model provides a kind of vehicle-mounted brushless motor with communication control, comprising:

[0008] Fixed ring is sleeved in the outer side of the shell of brushless motor, and is coaxial with brushless motor;Fixed ring is fixedly installed on vehicle frame;Spacing is equipped between the inner circle of fixed ring and the shell of brushless motor, and outer circle is abutted to the inner side of fixed ring;

[0009] Flexible buffer ring is installed in the inner side of fixed ring, and its inner circle is abutted to the shell of brushless motor;

[0010] The output shaft of brushless motor is connected with fan by universal coupling.

[0011] The beneficial effects of the above arrangement are: 1. The buffer ring makes the radial direction of the brushless motor contact with the frame softly, and the buffer ring also provides a buffer space for the radial direction of the brushless motor, so that the buffer ring protects the brushless motor, and when the automobile is vibrating, the brushless motor can realize radial displacement for a distance, so that the communication control will not be damaged; 2. When the brushless motor is radially displaced, it is easy to be misaligned with the fan, which can easily cause the connection between the brushless motor and the fan to break, so the setting of the universal joint allows the brushless motor to still stably drive the fan to operate without changing the position of the fan.

[0012] In order to improve the position accuracy of the buffer ring, specifically, an annular mounting groove is arranged in the fixed ring; and the buffer ring is clamped in the mounting groove.

[0013] Although the buffer ring can play a buffering role, the buffer ring also has a heat preservation effect, which can affect the heat dissipation effect of the brushless motor. Based on this, further improvement is that the buffer ring is provided with a plurality of first air holes penetrating the inner and outer walls.

[0014] The heat dissipated by the brushless motor is transmitted to the fixed ring through the first air holes, and then dissipated to the outside through the fixed ring, which is relatively low in efficiency. Based on this, further improvement is that the fixed ring is provided with a plurality of second air holes penetrating the outer wall and the bottom of the mounting groove, and the second air holes are in communication with the first air holes. In this way, the heat dissipated by the brushless motor shell in the area covered by the buffer ring is directly dissipated through the first air holes and the second air holes, which can improve the heat dissipation efficiency.

[0015] Since the first air holes and the second air holes are difficult to accurately communicate when the fixed ring and the buffer ring are connected, further improvement is that the bottom of the mounting groove is provided with an annular, recessed circular-arc-shaped ventilation groove; and the ventilation groove is connected with the second air holes. In this way, the first air holes, the ventilation groove and the second air holes form a stable heat dissipation air duct, thereby reducing the position requirements of the fixed ring and the buffer ring, and only the buffer ring needs to be clamped into the mounting groove.

[0016] Further, the outer wall of the buffer ring is provided with an annular, recessed circular-arc-shaped slot, and the opening direction of the slot is opposite to that of the ventilation groove. The beneficial effects of this arrangement are: 1. The arrangement of the slot increases the deformation space of the buffer ring, which can provide better protection for the brushless motor; 2. The arrangement of the slot allows the slot and the ventilation groove to form an air duct together, thereby expanding the flow area of the hot air flow to improve the heat dissipation effect.

[0017] The utility model also provides a fan which adopts the vehicle-mounted brushless motor with communication control. In this way, the fan is not easy to be damaged and can continuously and stably operate.

[0018] The utility model discloses a beneficial effect is: 1, the buffer ring makes the radial of brushless motor and the soft contact of frame, and the buffer ring still provides the buffer space of brushless motor radial, to make the buffer ring to brushless motor play the protection effect, when the car is vibrating, brushless motor can realize the radial displacement of a distance, make communication control not damage, 2, because brushless motor radial displacement, easy and the fan dislocation, easy to cause the junction of brushless motor and the fan fracture, therefore the setting of universal coupling makes the fan position not change the situation, and brushless motor still can stably drive the fan operation.

[0024] The utility model is now further explained in detail in combination with the drawings. These drawings are all simplified schematic diagrams, just with the schematic way to illustrate the basic structure of the utility model, therefore it just shows the structure related to the utility model.

[0025] Example one:

[0026] As Figures 1-3 The utility model provides a kind of vehicle-mounted brushless motor with communication control, including brushless motor 2, the outside sleeve of its casing is coaxially arranged fixed ring 1. Fixed ring 1 is fixedly installed on frame. The inner side of fixed ring 1 is provided with recessed, annular installation slot 5, flexible buffer ring 3 is clamped in installation slot 5, and its material can be selected rubber or cowhide. Installation slot 5 is used for buffer ring 3 installation limit.

[0027] The inner wall of buffer ring 3 exceeds the inner wall of fixed ring 1, so that the inner wall of fixed ring 1 and the casing between brushless motor 2 are provided with spacing.

[0028] Although the buffer ring 3 can play a buffering role, the buffer ring 3 also has a heat preservation effect, which will affect the heat dissipation effect of the brushless motor 2, so the buffer ring 3 is also provided with a plurality of first air holes 6 penetrating the inner and outer walls. The heat emitted by the brushless motor 2 shell covered by the buffer ring 3 is transmitted to the fixed ring 1 through the first air holes 6, which plays a role in dissipating heat in time.

[0029] The fixed ring 1 is provided with a plurality of second air holes 7 penetrating the outer wall and the bottom of the mounting groove 5. In this way, the heat emitted by the brushless motor 2 shell covered by the buffer ring 3 is directly dissipated through the first air holes 6 and the second air holes 7, which can improve the heat dissipation efficiency.

[0030] Because the first air holes 6 and the second air holes 7 are connected to play a role in dissipating heat in time when the fixed ring 1 and the buffer ring 3 are connected, and the first air holes 6 and the second air holes 7 are coaxial to play the maximum heat dissipation effect, the relative position accuracy of the fixed ring 1 and the buffer ring 3 is high, which leads to high installation difficulty, so the following design is made: The bottom of the mounting groove 5 is provided with an annular, recessed circular-arc-shaped ventilation groove 8; the ventilation groove 8 is connected with the second air holes 7. In this way, the first air holes 6, the ventilation groove 8 and the second air holes 7 form a stable heat dissipation air duct, thereby reducing the position requirement of the fixed ring 1 and the buffer ring 3, and only the buffer ring 3 needs to be clamped into the mounting groove 5.

[0031] The outer wall of the buffer ring 3 is provided with an annular, recessed circular-arc-shaped notch 9, and the opening direction of the notch 9 is opposite to that of the ventilation groove 8. The beneficial effects of this arrangement are: 1. The notch 9 increases the deformation space of the buffer ring 3, which can provide better protection for the brushless motor 2; 2. The notch 9 and the ventilation groove 8 together form an air duct, thereby expanding the flow area of the hot air flow to improve the heat dissipation effect.

[0032] Because the brushless motor 2 is easy to be misaligned with the fan when it is radially displaced, it is easy to cause the connection between the brushless motor 2 and the fan to break, so the output shaft of the brushless motor 2 is connected with the fan through the universal joint 4, so that the brushless motor 2 can still stably drive the fan to operate without changing the position of the fan.

[0033] Compared with the prior art, the beneficial effects of the present embodiment are: the buffer ring 3 makes the radial direction of the brushless motor 2 soft contact with the vehicle frame, and the buffer ring 3 also provides a radial buffering space for the brushless motor 2, so that the buffer ring 3 plays a protective role for the brushless motor 2. When the automobile is vibrating, the brushless motor 2 can realize a certain distance of radial displacement, so that the communication control will not be damaged.
